Joy: the highest mood of worship is joy. Shouting with joy accompanied the sacrifices because they brought about forgiveness (Leviticus 9:24). Shouting with joy accompanied the presence of God (Isaiah 12:6).
Thanksgiving: express one’s public proclamation or declaration (confession) of God’s attributes and his works. This concept is at the heart of the meaning of praise.
Bless: Bless the Lord is an odd phrase. Usually the blessing goes from the greater to the lesser, and in this case we are called to “bless the Lord.” Its answer may be found in noting that the root of the word is “kneel.” Just as Thanksgiving is a necessarily reciprocal activity (Thanksgiving has a subject and an object, you can’t be “thankful” without someone to be thankful to) blessing may have the same reciprocal characteristic. In order to receive God’s blessings, we must bless/kneel to Him in praise and Thanksgiving.
Grace Challenge Day 24 leads us into the final weekend. Fill tomorrow’s worship with shouts and songs of Joy, Praise and Thanksgiving, and bend then knee in worship so that you might experience the blessing of God.
